Cleveland C04601 Screw Machine Drill Bit 1/2 in Hss

Product Description

The CLEVELAND C04601 is a screw machine length twist drill bit designed for general-purpose hole-making in metal fabrication, machining, and maintenance applications. Built from high-speed steel with a bright uncoated finish, this bit measures 0.5000 inches in diameter with a 118-degree standard point angle and a web-thinned tip that reduces thrust and improves chip evacuation on entry. The shorter overall length of 3.75 inches provides added rigidity compared to jobber-length bits, making it well suited for drill press and CNC work where runout and deflection must be minimized. Licensed machinists, maintenance technicians, and metalworkers are the primary users.

The C04601 is used in drilling alloy steel, aluminum, and similar materials in both shop and field environments. Its straight cylindrical shank fits standard three-jaw drill chucks on bench-top drill presses, CNC machining centers, and handheld power drills. The short screw machine length is especially practical in tight clearance situations or when working inside fixtures and jigs where a longer jobber bit would be impractical. This bit ships individually and suits both low-volume repair work and higher-volume production setups that require a reliable general-purpose drill.

Key Features

• High-speed steel construction provides adequate hardness and toughness for drilling alloy steels and aluminum
• 118-degree standard point angle with web-thinned tip reduces entry thrust and improves centering
• Screw machine (short) length of 3.75 inches overall delivers greater rigidity and reduced deflection
• Right-hand cut with two regular spiral flutes for efficient chip removal
• Bright uncoated finish suitable for use with cutting oil or dry depending on workpiece material
• Meets ASME B94.11M standards with a diameter tolerance of +0.0000 to -0.0010 inches

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with any standard drill chuck accepting a 0.5000-inch straight cylindrical shank. Primary workpiece materials listed by the manufacturer are alloy steel and aluminum.

Installation Notes

A licensed machinist or maintenance technician should install and operate this bit. Always power down and lock out the machine before changing bits. Secure the straight shank fully in the chuck and verify there is no runout before drilling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
